The scientists writing in the journal, Proceedings of the National Academy of Sciences, say they completed the analysis of his blood in just 10 days.

They were able to see that he had a mutation on a gene that coded for a gut disease and tell his doctors.

Clinical tests proved that the boy had the disease and he is now recovering.

Simultaneous analysis

Richard Lifton, of Yale University Medical School who co-ordinated the research with teams in Beirut and Turkey, said: "The boys physicians sent a blood sample - they only had a very broad diagnosis of what was happening to this five-month-old child and were suspicious that he had a genetic disorder affecting his kidneys.

"Rather than looking one gene at a time hoping to guess which was the right gene causing the problems, we used a new method were we could look at all the genes in the genome simultaneously.

"We identified a particular gene which had mutations on both copies and which causes a fundamental problem meaning that the child could not absorb water or electrolytes through his gastrointestinal tract.

"We went back to the physicians in Turkey and said we think this is the problem and they confirmed it and are now able to give him better treatment."
